WebPumice, Scoria, and Cinders. Pumice, scoria, and cinders are specific types of highly vesicular pyroclastic rocks, although the distinction between them is somewhat arbitrary. Vesicles are small cavities in volcanic rocks that formed as bubbles that grew because of the exsolution of gases escaping from the magma upon eruption. WebScoria differs from pumice in being denser, with larger vesicles and thicker vesicle walls; it sinks rapidly. The difference is the result of the lower viscosity of the magma that formed scoria. When larger amounts of gas are present, the result is a finer-grained variety of pumice known as pumicite.

Figure \(\PageIndex{1}\): Pumice. An extreme version of scoria occurs when volatile-rich lava is very quickly quenched and becomes a meringue-like froth of glass called pumice. Some pumice is so full of vesicles that the density of the rock drops low enough that it will float.
